WebThe grating element calculations from the diffraction pattern will agree very well with the spacing measured from analyzing the AFM images. The spacing of tracks in a DVD is about half as that in a CD giving it twice as many tracks per mm. This accounts for about a two … WebWhat You Do: 1. Print the glasses template and carefully cut out only the temples (the piece that rests on your ears). 2. Next, carefully take the cardboard box apart creating one flat piece. 3. Trace the temple templates onto the cardboard and carefully cut out. 4. Next, build the bridge of the glasses that rests on your nose.
WebThe diffraction grating is an immensely useful tool for the separation of the spectral lines associated with atomic transitions. It acts as a super prism, separating the different colors of light much more than the dispersion effect in a prism. ... the closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar ... http://www.physics.smu.edu/kehoe/1301S06/cd_diff.pdf
WebCDs and DVDs contain regularly spaced micrometer sized features which can act like a diffraction grating.

While the drawing doesn't indicate scale, d (the groove spacing) is typically small -- much less than 1 mm. Common groove densities (1/d) are 300, 600, 1200, 2400, 3600, and 4800 grooves per mm, corresponding to d = 3.3333 µm to 208.33 nm respectively. ...
